希腊字母epsilon的两种写法ϵ,ε,一般认为哪个是原型,哪个是变体? - 知乎 注意到\epsilon的Unicode全名是「Greek Small Letter Epsilon」,即「小写希腊字母Epsilon」;而\varepsilon的Unicode全名则是「Greek Lunate Epsilon Symbol」,即「半月形希腊标志Epsilon」,并没有提到「字母」。
notation - What does the letter epsilon signify in mathematics . . . $\begingroup$ Historically, the symbol $\in$ is derived from $\epsilon$, thus it is not impossible to confuse both symbols Also, not as ubiquitous as its primary usage, this Greek symbol $\epsilon$ or $\varepsilon$ is also used to denote the sign, including Levi-Civita symbol in physics and random sign in probability to name a few $\endgroup$
analysis - What does $\epsilon$ mean in this formula - Mathematics . . . $\begingroup$ As an aside, the $\in$ takes its basic shape from the Greek letter $\epsilon$ The symbol $\in$ means "is an element of", so using the Greek letter that starts the word "element" as a design inspiration isn't entirely unreasonable $\endgroup$
